Re: yet Another 540i tech question... (archive)

The warr. from BMWNA is 6 years from orig. delivery date (in service date) or 100k miles. Whichever comes first. The cyl's are not sleeved, it is actually the block material that corrodes, hence that new material to replace it. ( for a full write up, check out www.530i.org )

As far as your question about it being fine @90k, if it is good now, many believe it will be fine down the road. But if the car is still covered under the warranty, I would go to a dealer and have the Tests done just to see how bad (if at all) it is.

1994 530i

First Off - thanks to all that responded to my earlier question - takes a load off my mind for sure! - here's another:

A friend of mine just bought the car (1994 540i) with 95K miles - idles very rough and rich (Oxy. sensors, we'll change next week - just in case) and I am afraid to tell him about the V8 cylinder sleeve problems many have experienced - so here's my question:

1. If the motor has never been replaced - at 90K miles, should I assume the thing is alright long term?

2. Is it a matter of "when" and not "if" the cylinder sleeves let go - what's the general warranty on such a catastrophe?

The V8s are new to me - and I'm helping him sort the car - so forgive my ignorance, guys.

All the Best - and TIA!
